RAILROAD-RAIL BOLT.

To all whom it may concern:

Be it known that I, REUBEN L. TIPTON, a citizen of the United States,residing at Safford, in the county of Dallas and State of Alabama, haveinvented certain new and useful Improvements in Railroad-Rail Bolts, ofwhich the following is a specification.

This invention relates to improvements in rail joints, and particularlyto a bolt used therefor.

One object of the invention is to provide a locking means for the nut,to hold the same from turning.

Another object is to provide a head on the bolt which will prevent thesame from turning.

A further object is to provide a bolt having a depending portionprovided with biting edges on opposite sides thereof, adapted to engagewith the upper face of an angle bar or the upper face of the base memberof a rail.

With these and other objects in view, the invention consists in theconstruction, combination and arrangement of parts as will be more fullyhereinafter described and pointed out in the claims, but it will beunderstood that changes in the specific structure may be made within thescope of the claims without departing from the spirit of the invention.

In the drawings: Figure 1 is a side elevation of a railjoint, showing myinvention applied thereto, Fig. 2 is a top plan view of the joint, Fig.3 is a section on the line 38 of Fig. 1, Fig. 4 is an enlarged detail,in side elevation of the bolt, Fig. 5 is an end view of the headed endof the bolt, Fig. 6 is a longitudinal section through the bolt and nut,Fig. 7 is a similar section to Fig. 3, showing the use of the fishplates, and the head engaging the base of the rail.

Referring to the drawings, 10 represents a rail having the angle bars 11disposed on opposite sides thereof, and having respectively, theopenings 12 and 13, through which is adapted to pass my improved bolt14. The bolt comprises a shank 15 having the ordinary threads 16 at oneend thereof, adapted to receive thereon the nut 17 Formed through eachface of the nut, and

extending into the threaded opening 18 is a passage 19, through which isadapted to be passed a pin 20, and formed vertically through thethreaded portion of the shank of the bolt, is an elongated opening 21,

which receives therethrough the pin 20 when the nut is adjusted to bringany one of the openings 19 in register therewith. The elongated opening21 is of slightly less width than the pin 20, so that when the pin isdriven through, it will bindingly contact with the sides of saidopening, and prevent the backing off of the nut. The bolt is providedwith a head 22, having the upper portion 23 in line with the shankthereof, and the depending bifur *ated portion 24:, the lower faces ofwhich are inclined upwardly and inwardly toward the rail, as at 25, toconform to the inclined surface 11 of the angle bar. The dependingportion has the two legs 26, which are of sufficient resiliency to bebent in a direction transversely of the head, so that any tendency ofthe parts to move which might cause the bolts to turn, would result inthe bending of one of the legs and the biting engagement of either ofthe edges 25 into the surface of the angle bar. Each of the legs 26, hasits lower face also inclined upwardly toward the arched opening 27, sothat the edges 25, only, engage the surface 11, it being thus seen thatit would be impossible for the bolt to turn.

As seen in Fig. 7, the legs of the head of the bolt are shown ascontacting with the upper surface 1.1 of an angle bar.

From the foregoing, it will be apparent that the bolt is effectivelyprevented turning by its head, and also the nut is prevented backingoft. Furthermore, in applying the bolt the same would be driven in tocause the edges 25 to bite into the surface 11, and any longitudinalmovement of the bolt, out of the openings in the angle bars and rail,would be effectively prevented by the trihedral angle 29.

lVhat is claimed is:

1. In combination with the meeting ends of a pair of rails and anglebars, of a bolt having a vertically arranged and elongated openingthrough one end thereof, a nut on said end provided with transverselyformed openings adapted to register with said elongated opening and toreceive a pin therethrough, said pin adapted to form a binding contactwith the side walls of said elongated opening, and a head on said bolt,provided with depending resilient spaced legs having biting edges.

2. In combination with an angle bar of a rail joint, a bolt having a nuton one end, means for locking said nut to said bolt, and

a head on the opposite end of said bolt having depending spaced legs,the lower faces of said legs being inclined upwardly and inwardly towardsaid angle bar, said faces also'being upwardly aiid inwardly inclinedtoward each other, whereby a biting edge is formed on each of said legs,and which is adapted to bite into the surface of said angle Jar.

3. In combination with a rail joint having fish-plates thereon, a bolthaving a nut on 'one end, means for locking said nut to said bolt, and ahead on the opposite end of said bolt having depending spaced legs, thelower faces of said legs being inclined upwardly and inwardly towardsaid angle bar,

said faces also being upwardly and inwardly inclined toward each other,whereby a biting edge is formed on each of said legs, and a bitingcorner formed at the intersection of the inclined edges of the faces,said biting edge and biting corner being adapted to engage into theupper surface of the base of a rail to prevent the movement of the boltin any direction. I

In testimony whereof I aflix my signature, in the presence of twowitnesses.
